Application ined August 9, 1911.

The objects of my invention. are: First.V

il, 111 and 1.5, of corresponding length and power. These springs aresupported by and arranged in position between two vertical frames 16 and17, rectangular in form and spaced apart the requisite distance, theframe 16 forming the front end of the motor trame, and the frame 17 therear end-of the motor frame. The vertical sides 16 and horizontal topand bottom portions 16, of the frame 16, and the like parts 17 x and 17D, of frame 17, are as shown flat plates, narrow in width. The lowerportions of the front and rear -frames 16v and 17 are connected rigidlyby the horizontal rods 18, the ends rigidly by the horizontal rods18,the ends of which rods extend through the lower corners yof the frameformed .by the junction of the vertical side plates 16c and 17, and thelower plates 16, 16X, of the front and rear frames 16 and 17,respectively. The upper port-ions of the frames 16 and 17 are connected-lrnily together by the rectangular frame`19, the ends of which frameextend horizontally from the upper surface of the upper plate 16, of theframe 16, to the frame 17. v i

20 and'Ql indicate the winding arbor 0r spindles for the upper, coiledsprings 12 and 13 respectively` the rear ends of which 17", of frame 17,a considerable distance downwardly from the line of the upper,horizontal plate 17 o. The forward ends of the spindles 20 and 21 extendthrough the opening 20c and 21X, in the vertical plates 16X, of thefront frame 16, and a short distance beyond the line of the '-'wrivardsurfaces of said plates, and upon the end of said spindles are ixedlvsecured the pinions 29.

and 24, respectively..

front. frame 16, to the saine extent as spindles 2O and 21, and upon thesaid forward ends ot' spindles 25 and 26 are fixedly secured the pinions27 and 28, respectively. The coiled spring 12 is secured in the usualmanner at the inner end' fixedly to winding spindle or arbor 20, itsfree end being extended upwardly and folded over the rod 29, the ends otwhich rod extend through the upper plates 16", 17, ofu the front andrear frames 16 and 17, above the lines of spring 12, and the free end ofthe coiled spring 14 is Y folded upon the rod 30, above Athe fold ofsaid spring, the ends of which rod extend lthrough the vertical plate 16l17", ot the 'frontend rear' frames. The free ends of springs 13 and 15are extended downwardly, and folded upon the .respective rods 31 and 32,below the folds of the springs, the ends of which rods extend throughthe vertical plates 165.17, and 16, 17, respectively,

.of frames 16 and 17.

Upon the inner end of each winding spindle a short distance inwardlyfrom the lines of the inner surface of plates 17", of frame 17, isloosely mounted the cog wheel 33, and between said wheel and the saidsurfaces of plates 17, a ratch'et'wheel 34 is iixedly secured to eachspindle. Upon the outer surface of each wheel 33 is pivoted a pawl 35,which engages with the ratchet wheel 34, said ratchet wheel beingv heldin engagement by the spring plate'36, on the side of the wheel, its freeend bearing on said pawl.

lVith the respective upper and lower, horio frame 17, are rigidlyconnected at a point equidistant from the plates 17X, a vertical plateor standard 37. In said standard, at a point' intermediate its ends isjournaledthe inner end of a. rotary power-transmitting rshaft 38, itsouter end `extending outwardly beyond the outer surface of saidstandard, and upon said shaft is a band wheel 39. Upon the inner end or'shaft 38, which extends inwardly a short distance from the line of theinner surface of standard 37, is keyed at 41, a large gear wheel 40,which rotates with said shaft and is in constant mesh with eachcog-wheel 33, on each winding spindle 20,421, 25 and 26.

The expenditure of power of one or more coiled springs through the largegea-rwheel 40 is controlled by apbrake band 42, secured at 43, at oneend, to the outer surface of the upper plate 17 0, of frame 17, theother or free end passing beneath and in contact with the lower surfaceof band wheel 33, thence extended upwardly and secured to the hooked,lower end 44, of'a brake operating.Y This lever `is provided at 46, in aboxing 47, on the upper surfaceo the top frame 19,1 and in a'yerticalline with the standard 37. Upon said frame 19; within the lever 45, issecured a notched segment plete 48. Upon lever 45 is a hand lever 49,

`face of plates and lianges 67, on thestud wheel 57, near the periphery,

Imanes and a spring-controlled detent 49", engaging with the notchedsegment plate 48, said detent and hand lever being connected wire 49 thelower end of the detent being extended at right angles inwardly, as seenin Fig. 4, to engage with the notches in the segment plate. The centralportion of the front frame 16 is composed of two integrally-formed wideplates 5() and 51, crossing each other in lines diagonal to the frame(see Fig. 5). ln the central portionof said plates 50 and 51 are slots52 53, drawn upon the same lines as described of the plates 50 and 51,the slots intersecting with each other at the point' where said linescross each other, the'outer ends of the slots extending a. considerabledistance in the direction of the respective spindles 20, 21, 25 and 26.In the cross plates 50 and 51, between the outer ends of the slots 52and 53 and the spindles 20, 21, 25 and 26, are screw-thread` ed openings54, in which are tted the screwthreaded inner` ends of the stud shafts55. Upon these shafts are mounted loosely the pinions or idlers 56,which areV approxilmately of the same circumference as the pinions 22,24, 27 and 28, and with ywhich the pinions 56 are in mesh. These pinionsare held ontheY shaft by cotter pins A55.

57 indicates the power wheel for winding the springs of the motor.V Thiswheel is large'in circumference, and is made or cast to obtain greatweight. AUpon the circunn ference of the wheel '57 `are cog teeth 58,which' mesh with the respective idlers or pinions 56, on the studshafts'55.

The power wheel is loosely mounted upon an adjustable bearing consistingof a sleeve byal 60, upon the inner end of which sleeve isl a flange.61, which' bearsupon the outer sur- 51 and extends past the lines of thesides of slots 51 and 52. Upon the inner surface of the wheel 57 is ahub 62, which `bears against the outer surface of flange 61. The sleeve60 is mounted'upon'the outer end of a stud shaftl 63, upon which outerend of saidshaft `is a reduced screw-threaded portion 64, upon whichportion is a washer 65, and a cla1nping nut 66, which bears againstwasher 65,

the latter bearing against the outer end of` the sleeve 60. The innerend of the stud shaft extends within theslots 52 Iand 53, at their pointof intersection, and upon the inner end of said shaft isa circularflange 67, .which bears against the inner surface u of the plates 50 and51 and extends `past they lines of the sides of the slats 52 and saaieshaft 63, and the flange 61 on the sleeve 60, acting to clamp theopposite surfaces of the plates 50 an l51, and support the stud shaft inposition,-

the sleeve being slightly longer than said shaft. Upon the outer surfaceof the power is an operating 'handle 68, ivliieliextends outwardlyashort distance therefrom.

ln the operationot' Winding the Spi-ings of the motor, which areshoWnfin'Figs. 1 and 2 expanded and ready to bej wound. the

brake lever 3 is first movedto the right and sutheient tension impartedto thehrake band to arrest motion "of the gear wheel. l.

Manual pouer is then applied to the handle (3S. on the power Wheel 57,and rotation iniparted to said wheel in a' right hand direc- -tion,communieatingoil` a reverse moveineiitto latter engagingwith the ratchetwheels Si,

the pinions 56, and aright hand movement to the'. pinions 22,241,27 and28. This morenient'turns the respective spindles 20. 2l and 25 and 2G,in the Asamedirection, drawing expanded coils ofthe springsfelosetogether upon the said spindles, reverse more-.-

monts of said .spindles being prevented b3v the gear wheel lt),with-.which .tliegear wheels are in mesh, the pavvl 35 in the 'windingotf the springs is-obtained with the expenditure ot'. minimum amount ofmanual power. Vlien'ever thewvinding' oa single spring is'desired, andsufficient power .is obtainable'troin one instead of -tl-ie springs i'nmultiple, tlie-pinions 5 6 and stud shafts 55,
